Poster Abstract


Bilarge Mixing of Leptons Using Abelian Flavor Symmetries

We present a model for the mixing of leptons based on non-renormalizable terms generated by the Froggatt-Nielsen mechanism and Abelian flavor symmetries. The model yields bilarge leptonic mixing, the hierachical pattern of charged lepton masses and an inverted neutrino mass hierachy. The leptonic mixing parameters and neutrino mass squared differences which are obtained are all conistent with the atmospheric neutrino data and the Mikheyev-Smirnov-Wolfenstein large mixing angle solution for the solar neutrino problem.
